GARBER, OF CUYAHOGA FALLAS, OHIO, ASSIGIII'OR T'O THE VAN DORN IRON WORKS COMPANY, OF CLEVELAND, OHIO, A CORPORATION. F OHIO .TAIL DOOR MECHANISM Application led May 9, 1930.-,Seria1 No. 450,992.

This invention relates to controlling mechanismy for the sliding doors of a row of jail cells. The mechanism is `of the type wherein all of the doors oi the row maybe locked against closing or against opening, or deadlocked, by gang mechanism; wherein the gang mechanism may be set to allow door movement inv one direction but not the other; and wherein the individual doors may be deadlocked independent of the gang mechanism, or the gang mechanism may be set to deadlock all of the doors against the individual door locks. Y

The object of the invention is to provide of a small number of parts, such a mechanism which shall be simple and rugged and substantially incapable of malfunction.

The exact nature of this invention' together with further objects and advantages thereof will be apparent from the following description taken in connection with the accompanying drawings in which Figs. 1 and 2 are front and side elevations respectively of an application illustrative of my invention, parts being broken away to show d etails of construction; Fig. V3 isa section as in the plane, of line 3-3 Fig. 1; Figs. 4i, 5 and 6 are views corresponding to Fig. 1 showing the mechanism in as many typical positions; and

Fig. 7 is an enlarged detail of parts 4of the mechanism positioned as in Figs. 1 and 4. v lVith reference now to the drawings, 1 is a housing arranged along above and in front of a row of jail cells for enclosing the-mechanism to be described, a cover not appearing being arranged to close the open front of the housing. Within the housing is the track or runway 2 along which moves ahanger 3 which is provided with a pair of rollers 4 trackingon the runway for the purpose. A barred door 5 is carried by the hanger 3 a portion of which extends downwardly through a suitable slot in the housing 1 for the purpose.

It will be appreciated that whereas only a single door with its immediately associated parts is illustrated, the showing is of one of a number of similar units comprising the usual row of cells.

Secured with the housing 1 is a bracket 6.

The bracket 6 isv provided with a pair of vertically extending slot openings 7, spaced in the Vdirection of door movement, and

and these faces are arranged at opposed angles'as indicated. n

Each of the latch bolts isv provided near its, upper extremity with anV opening 11.`

Carried by the bracket 6 is a lever 15 having opposed arms 12 and a downwardly extending arm 13. Each of thearms 12carries a located above the upper extremity of the i pin 14 extending into the opening 11 of one f of the latch bolts. It will be apparent that by movement of thelever arm 13 the latch bolts may be selectively lowered onto the Vhanger 3'to'engage the teeth of the latter.

The openings 11 aremuch larger than the Y pins 14; as indicated Vso that when the lever 15 is sopositioned that the left end latch bolt 9 is lowered, the other latch bolt 9a is raised, and the door maybe moved to the left from closed position, but not reclosed'; and so that when the lever 15 is so positioned thatl the right end latch bolt 9a is lowered, the other latch bolt 9 is raised, and the door may be moved to the right from open position, but not reopened; in either case the lowered latch bolt, owing. to its chamfered face 10 and the lost motion between its opening 11 and its pin 14, riding-over thel teeth 8 as the door gang bar 16 isprovided at one end with suitable operator-controlled mea-ns for positioning the bar wherebyv the described latch bolt means may. be set to allow door-closing but not door-openingV movement, so that when the door is entirely closed as in Figs. 1 and 4 the vdoor is so locked; or whereby the latch bolt means may be positioned to allow door-opening but not door-closing movement, so that when the door is entirely opened as in Fig. 6 the door is so locked. Also the gang bar may be moved from its position Fig. 4 still further to the left, as in Fig. 5, until the pin 14 moves to the bottom of the opening-11 in the right-hand latch bolt 9a, to deadlock all ot the doors ot the row or cells.

The door 5 carries at its lower extremity a tongue 17 having a pair of notches 1S, 19,and aligned with bolts 2O and 21 respectively when the door is closed.

The bolt 2O is associated iith the latch bolt 9a through a link including the bell crank 22, pull rod 23 and bell crank 24. The bell crank 24 has a pin 25 which lits into asecond opening 26 in the latch bolt 9a, similar to but located below the opening 11 therein. The proportion and arrangement of these connecting parts is such that when the gang bar 16 is set as in Figs. 1 and 4 to allow the door to close and there lock it, the bolt 2() will engage the tongue 17 as the door closes, so that the door will be locked closed both top and bottom: but when the gang bar is positioned as in Fig. 6 to allow opening of the doors, the bolt 2O will be raised clear of its notch 18 in the tongue 17.

rIhe bolt 2O also carries a projection 27 overlying the bolt 2S ot a lock Q9 individual to the cell, whereby having a key fitting in the lock Q9, the bolt 28 and thus the bolt 2O may be raised from the shown position Fig. 1 to unlock the cell door 5 regardless of the position of the gang bar 16, unless the latter be set as in Fig. 5 to deadlock the row. However, the described control ot the bolt 2O by the gang bar 16 may still be had, as the projection 27 may at any time be raised above the bolt 28, by upward movement of the bolt 20.

Beneath the lock 29 is a second lock 80 having a bolt 31 with which the bolt 21 is secured, so that engagement of the bolt 21 with the tongue 17 is controlled by a second key fitting the lock 30. Thus when the cell door 5 is closed it may by the lock 30 be deadlocked against opening, independent of both the gang control mechanism and the lock 29.

Iwhat I claim is: n

1. In combination with a-sliding jail door, rack means movable with the door, a pair of latch bolt meansV mounted for selective cooperation with said rack means, each to prevent `movement vthereof in one direction, and gang means associated with said latch bolt means :for control of the same whereby the door-may be selectively secured against opening or closing movement.v i

2. In combination with a sliding jail door, rack means movable with the door, a pair of latch bolt means mounted for selective cooperation with said rack means, each to prevent movement thereof in one direction but allow movement in the other direction, and gang means associated with said latch bolt means Jfor control of the same whereby the door may be selectively secured against opening or closing movement, said gang means being adapted to deadlock one of said latch bolt means against said rack means whereby the door may be deadlocked against movement in either direction.

3. In combination with a plurality of sliding jail doors, gang means including a pair of latch bolts for each door for securing said doors against opening, said gang means being adapted to deadlock one of the latch bolts of each door, and lock controlled means for individually releasing the doors each from its other latch bolt.

4. In combination with a sliding jail door, rack means movable with the door, latch bolt means mounted for cooperation with said rack means to prevent movement thereof in dooropening direction,V gang means associated with said latch bolt means for control of the same and for setting of the sam-e to deadlock said door, additional means for locking the door in closed position, and means associating said latch bolt means with said additional lock-ing means vthereby actuation of said gang means to deadlock said latch bolt means prevents unlocking ot said additional locking 5. J ail door carriage means comprising a hanger member mounted on rollers, means provid'ng a way for said rollers, a door carried by said hanger member, teeth on said hanger member, and means cooperative with said4 teeth .for controlling movement of the hanger on the way and hence corresponding movement of the door.

6. In combination with a sliding ail door, a member movable with the door and provided with teeth, a pair of latch bolts each mounted for sliding `movement. into the path ot said teeth, the bolts having opposite'ly bevelled faces, and means arranged to lower either latch bolt onto saidV teeth and providing a lost motion connection with the lowered latch bolt whereby the same may have a ratchet-likel engagement with said teeth to allow door movement in one direction but prevent door movement in the other direction.

In testimony whereof I hereby aliix my signature.
